Title: Vehicle skeleton structure
Inventor: YAMAZAKI SEIJI
IPC: B62D25/20
Filed: 2002-03-19
Abstract: <P>PROBLEM TO BE SOLVED: To fill powdery granule material 12 having hollow parts 12a or porous powdery granule material in a space inside a skeleton member 11 and/or a space surrounded by the skeleton member 11 and panel members therearound in pre-solidified state or without solidification.  <P>SOLUTION: An increase in the weight of a vehicle skeleton structure is suppressed by the powdery granule material having hollow parts or the porous powdery granule material.
